Struct MemoryPool 

pub struct MemoryPool {
    name: String,
    buffer_size: usize,
    max_buffers: usize,
    free_list: Mutex<RawMutex, Vec<Vec<u8>>>,
    total_allocations: AtomicUsize,
    cache_hits: AtomicUsize,
    pool_size: AtomicUsize,
}

Memory pool for efficient allocation/deallocation.

Memory pools amortize allocation costs by maintaining a free list of pre-allocated buffers.

Fields

buffer_size: usize

max_buffers: usize

free_list: Mutex<RawMutex, Vec<Vec<u8>>>

total_allocations: AtomicUsize

pub fn allocate(&self) -> PooledBuffer<'_>

Allocate a buffer from the pool.

pub fn name(&self) -> &str

Get pool name.

pub fn buffer_size(&self) -> usize

Get buffer size.
